摘要：

We study the lowest-order modifications of the static potential for Born-Infeld electrodynamics and for the theta-expanded version of the noncommutative U(1) gauge theory, within the framework of the gauge-invariant but path-dependent variables formalism. The calculation shows a long-range correction (1/r(5)-type) to the Coulomb potential in Born-Infeld electrodynamics. However, the Coulomb nature of the potential (to order e(2)) is preserved in noncommutative electrodynamics.
